Patented Mar. 1, 1921.

Application filed September 18, 1919. Serial No. 324,521.

To all whom it may comem:

Be it known that I, LOUIS LANE, a citizen of the United States, and atpresent residing at Habana, Cuba, have invented a new and ImprovedCasement-Window, of which the following is a full, clear, and exactdescription.

My present invention relates to windows of the general type known ascasement windows, and more particularly relates to a metal window frameand sash.

The general object of the invention is to provide frame parts of novelforms and cross sections, and so arranged that the weathering of thesash is made tight without expensive hand-fitting necessary with theusual frames for the assemblage of the various members.

A more specific object of the invention is to provide an embodiment ofthe same that may be produced from few elements of simple form andresultin in a stron and weather-tight casement by the. or inary methodsof manufacture employed in the quantity production of metal sashes andwindow frames.

It may be stated that in windows of the type referred to fiat contactsalone have not been sufiicient in.weathering the sash except where verycarefully fitted, while sloping contacts which have been devised forweathering the sash are usually effective only when used at the sill butless effective when used at the head. Also while such sashes could bedrawn tight at the lock bars, they were apt to be loose at the head orhinge jamb unless very specially fitted.

The stated objections and others as will appear are overcome b the novelconstruction of casement win ow hereinafter particularly described andclaimed.

Reference is to be had to the accompanying drawings forming a part ofthis specification, it being understood that the drawings are merelyillustrative of one example of the invention. 7

Figure l is a front view of a casement window embodying my invention andhaving two swinging sashes;

ig. 2 is an enlarged horizontal section on the line 22, Fig. 1; Fig. 3is an enlarged the line 33, Fig. 1; c

I Fig. 4 is a detail in horizontal sectionat the lock side of the sub ina window emvertical section on ploying a single sash, the view beinggiven to show the preferred form of the amb member of the window framein a singlesash construction;

Fig. 5 is a fragmentary horizontal section at the lock sides of twoadjacent sashes when employed with a frame having no mullion;

F i 6 is a detail in vertical section on the line 6-6, Fig. 2, the viewbeing given to show the ball bearing at the bottom of the window at thehinge side.

In carrying out my invention according to the illustrated example, awindow frame is provided designated generally by the numeral 10, and asash or sashes designated generally by the numeral 11. The side bar 12of the sash 11 at the hinge side of the sash, terminates at the outerportion in a curved hinge member 13, which fits a fixed hinge member 14roundedin cross section to conform to the interior curved surface ofsaid hinge member 13. Thefixed hinge member 14 is formed on or securedto the jamb 17 of the window frame, said fixed hinge member being hereshown as having a web 15 secured by rivets 16 to said jamb. Also in thejamb 17, is a concave depression 17 spaced from the fixed hinge member14, presenting a curved way in which the hinge member 13 has movement,said hinge member and the seat 17 being concentric with the hinge member14.

The side bar 12 of the sash has a leg or flange 18 directed laterallyinward toward the inside of the window and its edge is adapted when thesash is closed, to have close contact with flange 19 rigid with the jamb17 and here shown as consisting of a separate angle bar secured by therivets 16 to the jamb. f

The elements 13, 14, 17*,18 and 19 extend the full height of the windowfrom the bottom cross bar to the head or top cross bar and thearrangement serves to produce a weather-tight joint. I

A tubular metal stop strip 20 is secured to the flange 18 fastened inthe illustrated example by having nuts 20 therein which are engaged byscrews 20;

At the lock side of each sash the vertical side bar 21 thereof is formedwith a transversely-curved terminal 22, correspondin essentially withthe hinge member 13, and adapted to engage a mating rigid member on amullion or on an adjacent sash.

In the form shown in Fig. 2, a fixed member 23 engaged by the member 22of the sash is secured by a rivet 2 1 or other suitable securing means,to the stem 25 of mullion 26, T-shaped in cross section, there beingmembers 23 at opposite sides of the web 25 to be engaged by therespective sashes.

In Fig. 4:, the side bar 21 at the lock side tageously being connectedby a transverse post or elongated rivet 31, to the plate 28, said rivet31 having a sleeve 32 thereon to space the plate 28 and plate 30. Theflange 27 of the adjacent sash at the lock sideis adapted to have closeengagement with the plate 30. In the form shown in Fig. 2, the flanges27 of the sashes contact with the mullion 26. I e

The window at the top and bottom is formed to correspond with the sidemembers 13 and 22, in making-the sash weathertight at the topiandbottom. Thus the head or top cross bar 33 of the window frame, whichpreferably is Z-sha-ped in cross section, has rigid therewith -a bead 14corre sponding in crosssection essentially with the fixed hinge member14, and the top cross bar 12 -of the sash has atransversely curvedmember 13 corresponding essentially with the hinge member 13 and withthe curved lock side membere22 to conformto thesurface presented by thebead 14. Alsothe flange 18 at the innerside of the sash bar 12*? isadapted to lie closev againstv the de pending flange 19 of the head 33.r The bottom cross bar 34: of the window frame similarly is Z-shaped incross section and has rigidtherewith a bead 1 L? rounded in crosssection to be engaged by a corresponding curved terminal 13 on thebottom crossbar 12? of the sash. The bar 34: presents an upstandingflange 19* with which the adjacent'flange 18 onv the bar 12 con tacts.

The various window frame members and sash frame members are properlyreinforced 95 piece ea et e rending pla efi nd angle bars 35* areprovided on the bars 34 and 12'. l I

It is to be understood that the angles of the upright and horizontalmembers of the window frame and sash frame are joined in any approvedmanner. In practice also the sash has bottom support at the hingeside bya ball bearing indicated in Fig. 6, comprising a bearing plate 37 on thebottom cross bar 34: of the frame, and having an annular race for theballs 38, the lower edge of the curved hinge member 13 having an arcuatewear plate 39, applied thereto to rest on the balls. j

The character 20 indicates stops on the flanges 27 The stops 20 areadjustable by having slots to receive "the fastener bolts or screws. l

The, above described construction com prises an effective weather-tightjoint at the hinge side, while insuring free and easy movement of thesash on the hinge. An effective'weather-tight joint is alsoefi'ected onthe lock side, and theicontact of the inwardly-directed flanges on thesash bars withthe adj acent-fla-nges on the frameat the inner side ofthe window, insures a tight engagement of the sash both at the insideand the outside of'the windows a 7 It will be observed also that theframe parts are of simple form, strong and dur able, and comparativelyfew in number.

V I wouldstate in conclusion that while the is claimed as new is:
